EDVARD R. PYE, OF NEW YORK, N. Y.

SWEAT-KNIFE FOR CUTTING HAT AND CAP LININGS.

Specification of Letters Patent No.

To all whom it may concern:

Be it known that I, EDWARD R. PYE, of the city, county, and State of New York, have invented a new and useful Improved Tool for Cutting and Perforating Hat and Cap Sweats; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l, is a side view of my invention.

in the line x, Fig. l. Fig. 3, is a top or plane view of ditto. Fig. 4., is a side view of the tool at present used and hitherto the mostapproved one for the purpose.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to a tool, or implement for simultaneously cutting out and perforating fo-r sewing the trimming of hats and caps technically termed sweats.

The object of the invention is to economize in the construction of the tool, rendering them far more durable than usual and so arranging the parts relatively with each other as to insure a perfect adjustment of the same at all stages of their wear.

To enable those skilled in the art to fully understand and 'construct my invention I will proceed to describe it.

A, represents the handle of the implement which may be of wood, and B, is a metal bar provided with a tang which is driven in the handle and secures the bar thereto. The outer end of the bar B, has a right angular' projection C, with two parallel guides a, a, at one side of it between which a steel plate D, is fitted and allowed to slide freely. This steel plate is slotted longitudinally as shown at b, Fig. l, and a set screw c, passes through said slot into the projection C. By this mode of connection the plate D, may be adjusted higher or lower as may be desired. The lower end of plate D, is rounded and brought to a cutting edge, forming a knife or cutter.

To the lower part of the projection C, a pointed wheel E, is attached the pin or axis d, of the wheel passing into the projection C.

26,052, dated November 8, 1859.

The wheel E, is allowed to turn freely 0n its pin or axis d. This wheel is of steel and points e, are formed on its periphery at a distance apart corresponding to the length of the stitches with which the article to be cut, is secured to the hat or cap. The pointed wheel E, is by the side of the cutter D, and the edge of the latter is about on a level or a trifle below the ends of the points c, the cutter D, being so adjusted relatively with the wheel E, that the former will cut through the material while the points on the wheel will pierce it for the needle.

It will be seen from the above description that as the knife D, is worn by use it may be readily adjusted so as to always have a proper relative position with the wheel and when the cutter is worn out a new one may be adjusted to the projection C. The bar B, will last indefinitely. The wheel E, will also last a long time, the knife however wears rapidly, but in my invention a new one may be readily adjusted.

The tool in common use Fig. 4, has its knife ax, formed on t-he projection bx, of the bar B, and consequently when the knife is worn out the tool is useless and a new one is required. The pointed wheel 0X, is attached to an arm (ZX, which is adjusted in the arc of a circle and it will be seen that as the knife ax, wears the relative position of the wheel with it changes and the implement performs its work very imperfectly. It is also an cxpensive tool as one in constant use will last but about a month, the knife ax, requiring frequent sharpening.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is,

The employment or use of the knife D, fitted between guides a, a, on the projection C, of the bar B, and secured thereto by the set screw c, in connection with the pointed wheel E, attached to the projection C, the whole being arranged substantially as and for the purpose set forth.
